DUNE Phase II Enhances Neutrino Research Capabilities

The Deep Underground Neutrino Experiment (DUNE) is advancing its Phase II planning, which aims to enhance the capabilities of neutrino research. According to a recent report by the DUNE Collaboration, Phase II will include the addition of a third and fourth far detector module, an upgraded near detector complex, and an enhanced 2.1 MW beam. The fourth far detector module is described as a "Module of Opportunity," intended to broaden the physics opportunities while supporting the core DUNE science program with advanced technologies.

The report highlights several key areas of scientific exploration enabled by DUNE Phase II, including long-baseline neutrino oscillation physics, neutrino astrophysics, and investigations into phenomena beyond the standard model of particle physics. The document details the technologies and design concepts currently under consideration for both near and far detectors, emphasizing the importance of research and development (R&D) goals and prototyping phases necessary to realize these technical designs.

DUNE's Phase II initiative is positioned to complete the full scope of the DUNE project, which is expected to facilitate a multi-decadal program of groundbreaking science with neutrinos. The findings from this project could significantly impact our understanding of fundamental physics and the universe.
